摘　　要：在液化地层中进行钻孔灌注桩施工时易发生塌孔、缩孔等事故,施工过程存在较大质量隐患。文章结合太原市城市轨道交通2号线一期工程人民南路站围护结构钻孔灌注桩施工,根据工程地层和工艺特点,介绍钻孔灌注桩在液化砂层中的关键施工技术,可为今后类似的桩基施工提供借鉴。When drilling in liquefied formation, it Prone to collapse Shrinkage cavity etc. and it will cause many the quality hidden peril in the construction process. Based on the first phase project of Taiyuan Urban rail transit line 2 People South Road station, according to the features of bored piles construction technology, the key technological of bored piles for the building enclosure of subway station in liquefied formation are introduced, which can be referred for similar pile foundation engineering in the future.
